(12.04-en) IGEL UMS HA Services and Processes

• Handles all requests from the devices and the UMS Console.
• Talks to the devices.
• Executes jobs.
• Acts as a message broker for internal messages.

• Forwards incoming requests from the devices to one of the UMS Servers with load balancing.
  The UMS Load Balancer has a list of running UMS Servers and distributes the requests to them sequentially.

• Monitors the run status of the UMS Server and the UMS Load Balancer running on the same server and forwards it to the UMS Servers.
• Starts or stops the UMS Server or the UMS Load Balancer on request from a UMS Server.

• For the list of running processes, use the command:
  sudo ps -ef | grep RemoteManager
  where RemoteManager is the last part of the installation path; Adjust it if the installation path is different.
  Each process has two entries on the list.
• For stopping the processes, use:
  sudo systemctl stop igel-ums-watchdog
sudo systemctl stop igel-ums-broker
sudo systemctl stop igel-ums-server

• For stopping the processes if the stop with the init scripts does not function:
  sudo kill -9 xxxx
  where the ID of the process can be seen in the output of
  sudo ps -ef | grep RemoteManager
